此算法对基于多重取幂密码协议的快速运作是很有效用的。

The algorithm is useful to speed up the operation for some cryptographic protocols based on multiple exponentiation.

基于进入系统的时间，写操作具有幂等性(不管操作多少次结果都不变的性质，比如取绝对值的函数就具有幂等性)和交换性(操作顺序不影响结果，比如加法就具有交换性)。

Write operations are idempotent and commutative, based on the time they enter the system.

如果表达式不是常量，就调用另一个宏函数把值向上取整到2的幂。

Otherwise, if the expression is not a constant, another macro function is called to round up the value to a power of two.
